• A new simulation suggests that the Milky Way and Andromeda galaxies may not collide within the next 10 billion years as previously thought.
• The collision could be affected by the gravitational forces of smaller nearby galaxies, such as the Triangulum Galaxy and the Large Magellanic Cloud.
• If the collision does occur, it could trigger a burst of star formation and push away all the local galaxies, making the merged galaxy the only visible universe in 10 billion years.
• For humans, the collision would have catastrophic consequences, as the sun would expand and boil the Earth.
